Delixi frequency converter E series precautions

1. Why does the maintenance function of the inverter operate when the clutch is connected to the load? When the load is connected with a clutch, at the moment of connection, the motor changes sharply from the no-load condition to the area with a large slip rate, and the large current flowing through causes the inverter to trip over the current and cannot work. ...

The function of Delixi circuit breaker is to make the circuit breaker internal electromagnetic tripping when the electrical equipment produces short circuit, overload, etc., resulting in the circuit breaker disconnecting the power supply, and maintaining the safety of electrical equipment and personnel. When the electrical equipment is running, the circuit may produce abnormalities, which is the demand circuit breaker in the ...

It shows that the voltage regulator base is not voltage corrected, and the voltage regulator in this situation is like a transformer, the higher the input voltage, the higher the output voltage, the input decreases and the output voltage also decreases. This...

The disconnector is a kind of switching equipment that is mainly used for "blocking the power supply, reversing the operation, and connecting and blocking the small current circuit", without arc extinguishing function. When the barrier switch is divided into directions, there is an insulation distance between the contacts that meets the specified requirements and a significant disconnection mark; When in the azimuth, it can carry ...

1. The inverter runs with the motor at no load 1. To set the power and number of poles of the motor, the operating current of the inverter should be considered. 2. Set the maximum output frequency, fundamental frequency, and torque characteristics of the inverter. The general-purpose inverter is equipped with a number of VPf curves for users to choose.

With the continuous progress of industrial automation, inverters have also been widely used, energy conservation and environmental protection as the center of China's industrial economic development, in the direction of the sustainable development of China's industry, but also in the effective promotion of the sustainable development of China's inverter profession, so that I ...

Delixi plastic case circuit breaker is also called equipment circuit breaker, the external contact of the grounding terminal, arc extinguisher, tripper and operating organization are installed in a plastic shell. Auxiliary contacts, undervoltage trippers, parallel trippers, etc. Most of them are modular, very compact in structure, and generally do not consider maintenance ...

Delixi solid state relay and Delixi communication contactor are more used products, so what are the advantages of solid state relay relative to communication contactor, how should we choose when we can choose? 1. First of all, the solid ...

Voltage vf and v difference: The two have different meanings, vf on the battery indicates the feedback voltage, while v represents the capacity of the battery and is a unit of measurement of voltage. Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive/negative electrode material and uses a non-aqueous electrolyte solution. ​ ...

First, the iron core may not be able to suction power Causes: The power supply voltage is too low or fluctuates too much, the power supply capacity of the operating circuit is lacking or the wire is broken and the control contact is poor, the technical parameters of the coil are inconsistent with the application conditions, and the product itself is damaged. Solution: Turn up the power ...

When the VFD is viewed regularly, the power supply should be blocked, the operation of the VFD should be stopped, and the cover of the VFD should be removed. The first thing is to check the places that cannot be seen without downtime, or the places where it is difficult to find problems on a daily basis, as well as the inspection and adjustment of electrical characteristics. After blocking the VFD power supply, the main power ...

1. The capacitance is generally indicated by "C" plus a number in the circuit (e.g., C25 indicates the capacitance numbered 25). A capacitor is an element composed of two metal films that are placed next to each other and separated by an insulating material. The characteristic of the capacitor is first and foremost the communication through the DC block. The size of the capacitance is ...

Frequency converter is a widely used equipment in modern factories. This is a very expensive new type of equipment, and the maintenance price of the inverter is also very expensive, so in the process of using the inverter, we should pay attention to the use of the inverter. Thing...

Single-beam crane throughout the use of electric hoist as a lifting mechanism, with a simple structure, convenient use, widely used in some lifting tonnage small industrial and mining enterprises, domestic hoist crane throughout the use of conical rotor motor, cone motor structure than the general motor messy, ordinary method speed regulation is more difficult ...

Contrasting method The specific method is to let the problematic meter and the normal meter operate under the same conditions, and then detect the signals at some points and compare the two sets of signals measured, if there are differences, you can conclude that the fault is here. This method requires maintenance personnel to have considerable knowledge and skills.

Delixi CDI-EM60 series inverter is a high-performance inverter, with the following characteristics and use: Characteristic: 1. It has good stability and reliability to ensure the stability and safety of the system operation. 2. High degree, wide range of speed control, ...

(1) The drawing of the wiring diagram and the wiring table shall be subject to the request of GB6988.6-1993 in the "Production of Control System Function Table Diagram". (2) All electrical components and wires should be marked with letter symbols and wiring numbers that differ from those in the schematic diagram of the electrical circuit. Schematic diagram catalog number, final ...

Oil Regulator: Also known as non-contact inductive regulator or intelligent non-contact regulator (only the name of the company's own selling point). Forte: 1. No contact, no protection, impact resistance (especially instantaneous impact, 2 times of normal.) The reason for this is the slow response, which ...

The high-voltage circuit breaker (or high-voltage switch) is the primary power control equipment of the substation, which has arc extinguishing characteristics. When the system is in normal operation, it can intercept and connect the no-load and load currents of lines and various electrical equipment. When there is a problem in the system, it can quickly block the fault with the cooperation of relay maintenance.

1. If the two branch lines are connected, the current in the zero line flows to each other, which destroys the working current balance in the zero sequence current transformer and causes the leakage protector to malfunction. If you want to use the neutral line of the power branch line as the neutral line of the lighting branch line nearby, it will cause the leakage of the power branch line.
